Increase the size of the indicator in UIPageViewController’s UIPageControl

by

Scaling the page control will scale the dots, but will also scale the spacing in between them. 

pageControl.transform = CGAffineTransform(scaleX: 2, y: 2)

If you want to keep the same spacing between dots, you’ll need to transform the dots individually:

pageControl.subviews.forEach {
    $0.transform = CGAffineTransform(scaleX: 2, y: 2)
}

However, if you do this in viewDidLoad, the transform has been reset by the time the view appears, so you should do this in viewDidLayoutSubviews…

override func viewDidLayoutSubviews() {
    pageControl.subviews.forEach {
        $0.transform = CGAffineTransform(scaleX: 2, y: 2)
    }
}
